The choice of coagulant is a critical decision in any water treatment process, directly impacting efficiency, cost, and environmental outcomes. NINGBO INNO PHARMCHEM CO.,LTD. frequently addresses the common question: Poly Aluminium Chloride (PAC) versus Aluminum Sulfate (alum). While both are used for water clarification, PAC offers a distinct set of advantages that often make it the preferred choice for modern water treatment facilities.

Aluminum sulfate, or alum, has been a workhorse in the water treatment industry for decades. It functions by neutralizing the negative charges of suspended particles, causing them to aggregate and settle out. However, alum has several limitations. It is less effective in cold water and across a wide pH range, often requiring additional chemicals to adjust pH for optimal performance. Moreover, alum treatment typically results in significant sludge production, which increases disposal costs and creates environmental challenges. The residual aluminum left in treated water can also be a concern for drinking water quality.

Polyaluminium Chloride (PAC), on the other hand, represents a more advanced coagulant. Its polymerized structure provides a higher charge density, enabling it to neutralize contaminants more effectively and at lower dosages. This means less PAC is needed to achieve comparable or superior results than alum. The advantages of PAC over alum are particularly evident in its performance characteristics. PAC forms larger, denser flocs that settle more rapidly, improving sedimentation efficiency and reducing the load on filters. This rapid floc formation is a key benefit when seeking high-efficiency coagulant PAC.

From an economic standpoint, the lower dosage requirements and reduced need for pH adjustment chemicals make PAC a more cost-effective water treatment coagulant in the long run. The reduced sludge volume further contributes to cost savings by lowering disposal fees. Environmentally, the lower sludge production and minimized residual aluminum make PAC a more sustainable choice. Its ability to perform well in varying temperatures and pH levels also adds to its operational flexibility and reliability.

NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range of PAC products designed to meet diverse water treatment needs. By understanding the specific challenges of your water source and treatment goals, we can help you select the most appropriate PAC formulation. Whether you are looking to improve turbidity removal, reduce sludge, or enhance overall treatment efficiency, exploring the PAC chemical properties and uses will demonstrate its superiority.

In conclusion, while aluminum sulfate has served the industry well, Poly Aluminium Chloride offers a more advanced, efficient, and environmentally friendly solution for water treatment. Its superior performance, economic benefits, and reduced environmental impact position it as the coagulant of choice for many modern applications. NINGBO INNO PHARMCHEM CO.,LTD. is your partner in achieving optimal water quality through the strategic use of PAC.
